Question

Transcribed Image Text:Del's and Rodney's are two plumbing services in a gentrifying area of South East
London. Within the area they service, the two firms operate as a duopoly and
together serve one hundred percent of the available local market. One of their key
lines of business is visiting customer's homes to install a new shower rail. A student
project has been investigating the local plumbing business and has estimated the
following information for Del's and Rodney's:
Total demand for new shower rails per week is given by
P = 200 - 4Q
Where Q is total market demand and can be divided between Del's (qd) and
Rodney's (qr) such that
Q = qd + qr
Assuming that the marginal cost of serving an extra customer is £40 for each, and
that marginal revenue for Del is given by
MRd
2008qd - 4qr
And marginal revenue for Rodney is given by
MRr
Then
2008qr - 4qd
